Does sexual intercourse hurt? Is there a need forlubrication?

Sex can sometimes be painful for a woman if she is nervous or tense. Stress and fear can mean a womandoes not get sexually excited enough to producenatural lubrication,or that she involuntarily tenses her vaginal muscles, making penetration difficult. Sex can also hurt the first time a woman does it as her hymen may be torn.
If sexual intercourse is painful, using a lubricant can help to make it more comfortable. Whenusing a condom it is important that awater-based lubricant (such as KY Jelly) is used, asoil based lubricants (such as Vaseline or moisturising cream) can cause the condom to tear and break. Ensuring that the woman is as relaxed as possible, and that intercourse is initiated slowly, can also help to make things more comfortable.
If a woman experiences a deep internal or burning pain when she has sex, she should discuss thiswith her doctor, as it could be a sign that she has an infection or other medical problem.
Sex is not usually painful for a man (unless the penis is bent into an awkward position), so he should also check with his doctor if he experiences any pain during erection or intercourse.
